LUBRICATOR FOR CAR-JOURNALS.

SPECIFICATION formingpart of Letters Patent No. '764,621, dated July 5, 1904.

I Application filed October 27, 1903. Serial No. 178,784. (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER WEAVER, a citizen of the United States, residing'at Mountainview, in the county of Howell and State of Missouri, have invented a new and useful Lubricator for Car-Journals, of which the following is a specification.

The invention relates to an axleor journal lubricator for railway-cars.

The object of the present invention is to improve the construction of car axle or journal lubricators and to provide a simple, inexpensive, and eflicient device adapted to be readily applied to various kinds of railway-cars and capable of automatically lubricating the same when a car is in motion and of similarly preventing a flow of the oil when a stops.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts, hereinafte'r fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing an of the advantages of the invention.

In the. drawings, Figure 1 is a side elevation of a portion of a car provided with a lubricator constructed in accordance with this invention. Fig. 2 is a perspective View, partly in section. Fig. 3 is a detail view illustratin the construction of the valve.

Like numerals of reference designate corre-' sponding parts in all the figures of the drawings.

1 designates a can or reservoir designed to contain oil for lubricating the journals of caraxles, and the said can or reservoir, which may:

be square or any other shape in cross-section,

is preferably cylindrical when applied tethe' truck of a'railway-car of the form shown in Fig. 1. In applying the device to freightcars where the trucks are provided with two axles, as shown, a cylindrical can or reservoir is employed; but when the device is applied to a locomotive a reservoirfof rectangular car or train freight-car, as shown in Fig. 1; but when used on mail, passenger coaches, and the like having trucks with three axles the reservoir or receptacle 1 will be provided with three oil-distributing tubes. The reservoir or .receptacle is provided at the top with a filling aperture having a screw cap or closure 3,- adapted to be readily removed for supplying the reservoir or receptacle with a lubricant. The reservoiror receptacle isheld upon the truck 4 by straps 5, constructed of metal and secured to the receptacle and to the upper tie-bar of the truck, as indicated in Fig. 1; but the receptacle may be mounted on the truck in any other desired manner. The distributing tubes or pipes incline downwardly from the reservoir or receptacle, and they are provided at their lower ends with verticalportions 6, which communicate with the journalboxes 7. The upper ends of the distributingpipes are provided with interiorly-arranged upright portions 8, located within ithe reservoir or receptacle, and receiving.- valves-9,

nal-boxes. portion 8 is provided with a valv e seat 10, and it has perforations 11 located above the valve-seat andjadapted to permit the oil to flow freely into-the'upper portion of the distributing tubes-orpi'pes. The valves are held in engagement With the seats when a car or train is stationaryby means of a plurality of coiledsprings 12, interposed between the bottom .of the reservoir or receptacle and the vertically-movable plate 13, to which the stems 14 of-"t'he valves are secured. The plate 13,

'which' is provided with perforations to permitthe 'oil to pass readily through it, has a series of,'guide-rods 15 depending from it and receiving and supporting the coiled springs 12. The stems 14 of the valves are fixed to the vertically-movable plate or head 13, which is fixed to the lower end of a vertically-movable piston or plunger 16. The piston or plunger 16, which extends to the bottom of the. body 17 ofthe car when the said body 17 is in a horizontal position and is stationary, is adapted to be depressed or forced downward by the rocking of the bodyof the car, whereby when the car is in motion the valves will be opened at intervals by the rocking of the car body and oil will be supplied to the journals. The top of'the reservoir orreceptacle is provided with a central aperture, and it has a stuffing-box 18, through which the plunger or piston-rod passes and which prevents any leakage of the oil. Thecar-body forcesthe plunger downward, and the springs, which are interposed between the head or plate13 and the bottom of the reservoir or receptacle, force the plungerupward and hold the valve normally closed. The upper end of the'plunger is provided with a buffer-19 of some elas tic material, 'and'the plate or head l3'is preferably reinforced by a bar 20at the point of attachment of the valve-stems, whereby the plate or head 13 is stiffened and is prevented -fro'm bending when the lubricator is iii-opera;

.tion. i

The lubricator,'which is adapted tobe readily applied to a car, is automatically operated by the rocking of the car-body, and it is capable of positively lubricating the journals of. a car while the same is in motion. Also the lubricatorwill gpositively cut off the flow of oil as soon as a car or train is brought to a standstill. T

' Having thus fully described my invention,

what I claim asnew, and; desire to secure by Letters Patent, is

1. In a car-axle lubrica'tor, the combination with a car, of a reservoir or receptacle mounted uponthe truck and provided with a tube for conveying the lubricant to the latter, said reservoir or receptacle being located above the ournal-boxes to provide a gravity-feed,

a spring-actuated device arranged within the reservoir or receptacle and having a valve normally closing the said tube, and a plunger connected with the said; device and arranged to be operated by the car-body when the car is in motion, substantially as described.

2. Alubricator comprising a reservoir or receptacle, a plurality of. distributing-tubes extending from the reservoir or receptacle, valves for controlling the flow of the lubricant through the tubes, a piston arranged to be engaged by the body of a car and provided with a head connected with the said valves, and a spring for holding the valves normally closed and for moving the piston in one direction, substantially as described.

3. A lubricator comprising a reservoir or receptacle, a plurality of distributing-tubes extending from the reservoir or receptacle and having interiorly-arranged portions provided with valve-seats, valves for controlling theflow of the lubricant through the tubes, a piston arranged to be operated by the body of acar' and provided with an interiorly-arranged head connected with the valves, and a spring for holding the valves normally closed, substantially as described.

4. A lubricator comprising a reservoir or receptacle, a plurality of distributing-tubes extending from the reservoir or receptacle, a

vertically-movable piston piercing the reservoir or receptacle and provided with a per 'forated'plate or head, valves controlling the .flow'of the lubricant through the tubes and having stems connected with the plate or head, springs interposed betweenthe plate or head and the bottom of the reservoir or receptacle, and means for supporting the springs, substantially as described. 1 I I 5. A lubricator comprising a reservoir or receptacle, a plurality of distributing-tubes having interiorly-arranged' upright portions anghprovided with valve-seats, valves engaging the seats and having stems extending through "the upright jportions, a plunger 0r piston having a head connected with the valvestems, and springs engaging the head and holding the valves normally closed, substantially as described.

In testimony that I claim the foregoing as my own-I have hereto affixed my signature in the presenceof two witnesses.
